Wi-Fi & routers

Guest Wi-Fi network isn't working

A guest network that won't connect or gives no internet is usually disabled in the router settings, misconfigured, or has an isolation setting blocking access, and is fixed from the router's guest network settings page.

Symptoms

  • Guest network doesn't appear in the Wi-Fi list
  • Guests can connect but have no internet access
  • Guest devices can't reach shared printers or smart devices (often intentional)
  • Guest network password isn't accepted

Likely causes

  • CommonGuest network toggled off in router settingsGuest networks are often off by default and need to be manually enabled.
  • CommonGuest network internet access disabled by mistakeSome routers have a separate toggle for whether the guest network can reach the internet at all.
  • PossibleClient isolation working as designedGuest networks intentionally block guests from seeing other devices on your main network, which is normal, not a bug.
  • PossibleGuest network password recently changed or expiredSome routers let you set a time limit on guest network credentials.

What to do

  1. Log into the router's admin page or app and find the 'Guest Network' section, usually under wireless settings.
  2. Confirm the guest network is toggled on and has a name and password set.
  3. Check that 'Allow guest internet access' or similar is enabled, separate from just turning the network on.
  4. Restart the router after making changes, since guest network settings sometimes need a reboot to apply.
  5. Reconnect a test device to the guest network and confirm it can load a webpage.
  6. If guests need to access a printer or smart TV, disable client isolation for the guest network if your router offers that option.
  7. If the guest network still won't work after these checks, check for a firmware update, since guest network bugs are sometimes fixed in updates.
